Experiment 1: Path integration by memory-impaired patients (MTL) and CON. (A) Performance as a function of the distance traveled to find the tile. When participants were disoriented by rotation (squares), they were no longer able to rely on self-motion cues and failed to path integrate. (B) Performance as a function of the time taken to find the tile. (C) Performance as a function of the number of turns made to find the tile. The dotted line indicates chance performance (90° error). *Denotes above-chance performance. Brackets show SEM.
